Text: Byrds (The). Fifth Dimension. What's Happening?!?!.
I don't know who you think you are
I don't know what you're doing here
I don't know what's going on here
I don't know how it's supposed to be
I, I don't have the vaguest notion
Whose it is, what it's all for
I don't know, I'm not crying
Laughin' mostly as you can see
Fifth Dimension
The Byrds
